Super Simple Dice Tray

Super simple dice tray I made to play D100 Dungeon. It has a little shelf to put the dice on when they are not in play.

I added the felt using a thin bead of hot glue along the edges of the box. So far it's held up just fine. I used hot glue instead of spray adhesive so that it would be easier to replace if it got grimy in the future. the main box is 15cm x 15cm.
